Amsoil(ATF) trans fluid???

[daman]

Trying some out in the wife's '03 Montana to see how it
compares to my M1,my question is i'm sure this oil will
go 100,000 miles?,i'm doing a complete transmition line flush
out,so when i'm done should be 100% Ams..in there..

van will not be used to tow,,,normal use..will not get
serviced again untill 100K,,will it do it????????

 

[JHZR2]

what does the amsoil literature say???

Considering that Dex III in the late 90's was considered 100k fill in many non-severe use passenger car and truck applications, it very well could be 100k fill.

Do you consider M1 ATF a 100k fill?

I consider both more robust, transmission life-extending fluids, with that being their main purpose. Refills even every 30k are a small price to pay compared to a rebuilt trans. At 30k, one could do a UOA and determine what kind of real life they might obtain.

Ams says under normal use 100k,,i've taken M1 out to 40-50k
before and it still looked ok yet(no UOA)..

i guess i'm wondering if anyone's done it..

 

[Whitewolf]

Assuming that they have not 'fiddled' with the formulation then I think that for non-severe use it probably would do 100K in a pre 2005 Hydramatic.

 

[Pablo]

Sure there is no reason why it shouldn't go 100K in normal service. I have drained quite a few cars with factory fill at 100K. Never have I analyzed the fluid, but it was still functioning. (ugly and smelly, yes)

Again if you are doing a true full flush, you will be fine.

 

[daman]

K...cool, i'll give it a try,keeping and eye on things as
mileage climbs,maybe even a UOA...


if anyone's taken this oil out this far could you post up
so i know how your experience went,or what was the mileage
you took it to????

 

[Steve S]

Hard to say how long the oil will last. The operating temps of the oil, what kind of driving "around town or freeway" and how much wear the trans puts out .Maybe the filter. How does/did the old oil look?

 

[daman]

Last dump was 40+K and it looked good yet,a tad darker then
new but smelled fine i thought,could have gone longer i'm sure..

i don't have a problem changing it out sooner but curios if
it'll go the distance,but i'm not going to jeopardize my trans over it..lol

If you want to go to 100K then I would install a Magnefine or similar filter. Sure the ATF will last 100K, but do you really want all those wear metals floating around for 100K?

If it was me, I would install the filter and do a UOA at 50K.

 

[Donald]

Given the cost of synthetic ATF, a UOA is reasonable at 50K.

My mechanic friend says it's bad medicine to change out dino ATF with high miles on it and replace it with synthetic. Believes it's a precurser to a tranny failure. He's a good mechanic and honest to a fault, but he's also a proponent of 3k oil changes. What's been your experience Pablo? What's your info to back up what your practices are?

Define "high miles". First of all, if you have a tranny with 300,000 to 400,000 or more miles which may be nearing end of life with conventional ATF, the AT probably won't benefit a whole lot by switching to synthetic ATF. Under 200,000 miles? No problem. Never had an AT fail by changing to synthetic ATF. Never had a mechanically fine AT die by flushing with conventional ATF or synthetic ATF. The problem mainly is that no ATF of any type will revive an mechanically unsound AT, but many mechanics will blame the fluid change if it fails within the next 10,000 (or whatever) miles.

I have seen several transmissions, which were shifting fine up to that point, have catastrophic failures after pan drops or flushes. Some had even had routine services before that, with no problems. I've seen way more have no problems, but it does happen.

My theory is that the fresh fluid breaks lose contamination, which then clogs a port or holds a check valve in the wrong position.

I've taken to doing an AutoRx treatment before any service, to make sure it's gently cleaned first.

Hey Pablo !


The original trany fluid was in until 71k on my '03 GMC Sierra (GM service guy said it looked "Very Clean"). Dropped the pan then & did a filter change.

At 107k, I did the T-Tech & 100% Amsoil Tranny fluid change.

So Pablo, If I wanna keep this baby a LONG time and I tow 3,000 boat & haul wood much more than most people, when should I pan drain or 100% exchange again...???

Thanks...

Magnefine is a sponsor and there should be the ad on top of the page. Its there for me.

Install a filter (Magnefine) and do a UOA at 30-40K Your use should be considered severe (or close to it) and I would plan on another full exchange at 50K unless the UOA says different (as in sooner).

Boy that Magnefine for your oil filter is a little pricy,how
long does it last?? the the one for the trans ain't to bad,just
don't like the idea of cutting my lines to install it..

 

[Dick in Falls Church]

Years ago, I ran the AMSOIL ATF (of that period) in a used Dodge van for abotu 120,000 miles. When the van rusted away to the point it wasn't worth keeping, I pulled an ATF sample before sending to the crusher. Report came back that fluid was suitable for continued use. It was a tad darker than the new stuff (which was likely a newer formulation) but still clear.

If the thought of leaving it in for 100,000 miles is overwhelming, change what is in the pan at 50,000.

The Magnefine is $15 I think. Is that pricey for a filter that will go 30K miles and help to keep your tranny running fine?

I believe I read 30K is the suggested interval, but I could be wrong.

That is only a little more than the Amsoil Ea filter for your engine.
